How Does the pool/spa heat pump work?
In the Heating Mode...
Sun-warmed air is the energy resource utilized by heat
pumps. The heat pump draws in and upgrades large quantities of low-grade
heat already existing in the air and transfers it to the pool and spa water.
This is accomplished by utilizing minimal amounts of electricity and freon
gas, along with a high powered fan, super-efficient compressor and your
already existing pool pump. The process is similar to your refrigerator
or air conditioner, only in reverse.
1) Large quantities of warm air are drawn through the evaporator coils by
a high-powered fan.
2) Freon liquid inside these evaporator
absorbs the heat from the drawn-in air, changing the freon liquid into warm
4) This compressed hot freon gas is then pumped through the
outer casing of the freon-to-water heat exchanger where it releases its heat
to the pool or spa water passing through the inner casing of the heat exchanger.
The now warm water is released back into the pool or spa for recirculation
through the heat pump until the desired temperature is reached. The freon
gas condenses back into a liquid state and is pumped through the system back
to the evaporator coils to
3) The warm freon gas is then passed through a compressor - which compresses
or reduces the volume of gas while substantially increasing its temperature.
